Population: Analysis and Models presents a discussion of demographic analysis and models. This book has been translated from French to provide access to an integrated textbook aimed at the French equivalent of undergraduates. The book is organized into two parts. Part I is devoted to analysis and is subdivided into two sections. The first section deals with elementary analysis or the steps that must precede an analysis of any complexity. It comprises three chapters: after an introduction, it presents the analysis of the results of one census followed by a summary of the analysis of population change during a year. The second section focuses on the analysis of demographic phenomena—nuptiality, fertility, mortality, mobility (migration) and on the population change that is their result. Part II deals with models, namely models of population dynamics, models of family formation following marriage, and nuptiality models. This book has been written for students with very diverse backgrounds, some of whom may have scarcely more than an elementary knowledge of algebra.
